Purpose: The purpose of this study was to determine the mortality at postoperative one year & the factors related to mortality for patients who are over 65 years old and who have a hip fracture.
Materials and Methods: The subjects of this study were 298 patients older than 65 years and who were operated on by one surgeon from 1995 to 2009.
Results: The one-year mortality rate for the over 65 years old patients with hip fracture was 15.8%. The one-year mortality rate was significantly related with the number of underlying diseases and with age of over 80 years old, but not with gender, the cause of trauma, the type of fracture, the operative methods, previous activity & the severity of osteoporosis. We found that 21.3% of the overall deaths occurred within 1 month and 57.5% of that occurred within 3 months.
Conclusion: The one-year mortality rate for the over 65 years old patients was 15.8%. The 1 year mortality rate for the over 65 years old patients was highly affected by the number of underlying diseases and an age of over 80 years old. As the majority of deaths occur within 3 months, intensive care is important during this period.
